By that logic, isn't requiring any form of identification treating "voters as guilty of fraud until proven innocent?" Or can we just approach now, say I'm so and so, and vote, no questions asked? That's the only way someone could be treated as beyond reproach.

By that logic, we should require everyone to derive Calculus from scratch, because "Hey, Newton had to do it on his own." The reason we are where we are today is because people passing on what they learned before decreasing the amount of time for the next person to learn the same concepts.
